最近一个时期,社会对气象厅在每次地震时所公布的烈度评价很坏,据说是因为它与一般人的实际感觉差异很大。例如:1月10日黎明时分关东地区发生了地震。气象厅公布的是:千叶、甲府、熊谷等地烈度为Ⅰ(微震),而按理说烈度应为0(无感)的东京、横滨等地区却晃动得使一些人惊慌地跳起。由于烈度是根据观测者本身的感觉、周围的晃动方式以及受灾情况判定,所以观测人员技术的熟练程度、建筑物构造及地盘情况的不同造成了微妙的差异。想预报东海地震,至今却还依赖主观
In recent days, the social assessment of the intensity of the earthquake released by the Meteorological Agency for each earthquake was said to be very bad because it is very different from the actual feelings of the average person. For example: January 10 at dawn when an earthquake hit the Kanto region. Meteorological Agency released: Chiba, Kofu, Kumagaya and other places of intensity I (microseismic), and arguably that the intensity should be 0 (no sense) Tokyo, Yokohama and other areas are shaking so that some people jumped up in panic. Because the intensity is determined by the observer’s own feelings, the way of shaking around and the situation of the disaster, the observer’s technical proficiency, building structure and site conditions caused subtle differences. To forecast the East China Sea earthquake, so far it still depends on the subjective
